VILLIAM H. WARD, OF BOSTON, MASSACHUSETTS; HENRY H. COTTON EXECUTOR OF SAID \VARD, DECEASED.

OPERATING VALVES lN WATER-CLOSET TANKS.

SPECIFICATION forming part of Letters Patent No. 449,770, dated April 7, 1891.

Application filed June 16. 1890. Serial No. 355,593. (No model.)

.the subsidence of the water therein after the valve has been raised to supply water to the bowl of the water-closet.

The invention consists in the combination, with a water-closet valve of any suitable construction, of a lever pivotally connected to a fixed support above the tank and adapted to be connected at one end tothe valve, its other end being adapted to be connected with the pull or contrivance in the closet through which the lever is moved to open the valve, a latch or link pivoted to the lever, a detent which is automatically raised so that it is normally in position to co-operate with said latch in holding the lever in its valve-opening position, and a connection between said detent and a float-lever, whereby upon the subsidence of the water in the tank the detent is displaced, so that the latch is released and the valve-supporting end of the lever allowed to fall and permit the closing of the valve.

The invention also consists in certain de-' tails and minor combinations of parts, all of which I will now proceed to describe and claim.

In the accompanying drawings, forming a part of this specificatiomFignre 1 represents a perspective view of a portion of a watercloset-supply tank provided with myimproved valve-operating devices, the valve being omitted. Fig. 2 represents a sectional view The same letters of reference indicate the same parts in all the figures.

In the drawings, (t represents a water-supply tank, and b represents the valve which is arranged to control the escape-opening at the bottom of said tank in the usual manner, said valve being of the usual or any suitable construction, and preferably provided with a stand-pipe b, which permits the escape and overflow of water from the upper portion of the tank when the water reaches the upper end of the stand-pipe.

0 represents a lever, which is pivoted at d to cars on a bracket or support 6, which is suitably attached to the upper portion of the tank, one end of said lever projecting over the interior of the tank, as shown in the drawings. The inner end of the lever is connected by a chain or other suitable means with the valve 1) and its outer end is. connected by a rod or otherwise with a pull or other contrlv ance in the water-closet, whereby the lever is moved when desired to open the valve. I

7L represents a latch or link pivoted at 7 to the lever c and adapted to swing freely on said pivot. As here shown, the free or swinging end of the link or latch rests loosely on the bracket 6.

j represents a detent which projects above the upper surface of the bracket e and is adapted to move vertically in a hole in said bracket. The lower end of the detent j is pivoted at 7a to a lever m, which is pivoted at n to cars s s on the brackets e. One end of said lever is provided with a weight 0, which normally acts to hold the lever m and detent j in the position shown in Figs. 2, 3, and 4, its upper end projecting above the upper surface of the bracket e. The detent j and link orlatch h are relatively arranged, so that when the inner end of the levercis raised, as shown in Fig. 3, to open the valve the swinging end of ,the latch will engage the projecting end of the detent and will be raised thereby to hold the lever c in the position last described. The end of the lever on opposite to that which carries the weight 0 is connected by a chain 19 with the float-lever q, said lever being connected with the cock that controls the admission of water to the tank and provided with a float g, which is supported by the body of ol the water.

water within the tank the water-admitting; cock being closed by the upward movement of the float caused by the rise of water in the tank and opened by the downward movement of said float caused by the subsidence \Vhen the float is at the height at which it is supported by the water when the upper surface of thelatter is at the upper end of the stand-pipe, as is shown in Figs. 2 and at, the chain 1') is slack and the lever qhas no effect upon the detent-supporting lever m; but when the water has been lowered by the opening of the valve the descent of the float-lever q causes it to draw the end of the lever m, with which it is connected by the chain 1.), downwardly until the detent is retracted far enough to release the link or latch 7L, and thus release the said link or latch and the lever and permit the valve-supporting end of the lever to fall, as shown in Figs. 1 and 2.

I do not limit myself to the details of mech' anism here shown and described, but may vary the same in many respects without departing from the spirit of my invention.

I claim 1. The combination of abracket or support adapted for attachment to a tank, a valvecontrolling lever pivoted to said support, a link or latch pivotally connected to said lever, and a movable detent which is normally held in position to engage said link or latch and through the latter to hold the lever in its valve-raising position, said detent being movable from its normal position to release the latch and permit the closing of the valve, as set forth.

2. The combination of a supply-tank, a bracket or support attached to the upper portion thereof, a lever pivoted to said support and connected at one end with the outletvalve of the tank, a link or latch pivoted to the lever, a movable detent arranged to cooperate with said link or latch in holding the lever in its valve-raising position, aweighted lever which normally holds said detent in its operative position, a float-lever within the tank, and a connection between the float-1ever and the weighted lever, whereby the latter is depressed by the descent of the floatlever and thereby caused to displace the detent from its operative position, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of June, A. D. 1890.
